COMPARISON GUIDE
InBody vs DEXA: Which Body Composition Scan Is Right for You?
InBody and DEXA are two of the most common body composition testing methods. Both move beyond a bathroom scale to show what your body is made of, but they use different technology and suit different needs. This comparison is balanced — neither method is universally better.
| Feature | InBody | DEXA |
|---|---|---|
| Technology | Multi-frequency bioelectrical impedance | Dual-energy X-ray absorptiometry |
| Radiation | None | Low-dose X-ray |
| Scan time | ~60 seconds | 5–15 minutes |
| Cost per scan | $30 at Alpha 1 | Typically $100–$250+ |
| Repeat tracking | Fast, radiation-free — ideal week-over-week | X-ray exposure limits frequency |
| What it measures | Segmental lean mass, visceral fat, water, phase angle | Bone density, fat mass, lean mass |
| Segmental breakdown | Each arm, leg & trunk independently | Regional, less granular per limb |
When InBody fits best
- Frequent, repeatable tracking without radiation
- Affordable per-scan cost ($30)
- Segmental lean mass per limb
- Monitoring GLP-1 muscle retention
When DEXA fits best
- Clinical bone density measurement
- Research-grade reference scans
- Infrequent, detailed baseline
